Specification of. Letters Patent.

Patented Nov. I5, 1192i.

Application filed December 27, 1920. Serial No. 433,167.

The object of the invention is to provide a practical and efiicient formof construction for a non-leaking valve, for the faucet or cook of'adraft tube, and which is equally well adapted for drawing hot or coldliquids or gases, or .for drawing liquids containing any solid substanceas a sediment" 'or grounds, which by remaining upon the valve seat wouldmake it impossible to completely close the valve in the faucet.

To avoid the disadvantages found in the use of a faucet that will notclose tightly under all conditions, and from which the liquid is alwaysdripping, I have employed the multiple form of valve and operating meanstherefor, and the mode of construction and combination and thearrangement of parts, hereinafter described, is shown in theaccompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings Figure 1, is a vertical central section ofthe device, showing the device open. Fig. 2, is a bottom plan thereof.Fig. 3, is a vertical section showing the valve closed.

In these figures, the valve is illustrated in connection with its use ina faucet adapted for drawing a liquid such as coffee, and in which thevalve is operated by means of a lever, that is' actuated by means of thereceptacle or container, such as the mug, or saucer for example when themug or saucer is passed underneath the spout of the faucet, in the actof drawing the liquid from a reservoir, to place it in a position to befilled therefrom.

In these figures, A, is the outlet opening of a draft tube, from whichthe liquid is drawn; B, is the tube through which the liquid passes tothe valve; C, is the valve chamber, comprising an enlargement of thetube B, closely adjoining the outlet opening A. i

In this chamber are positioned a multiple number of horizontalpartitions having valve seats D, E, and F, respectively, and having acommon vertical axis, and on these seats, a corresponding number ofvalves are seated, G, H, and I, respectively.

These seats and valves are successively smaller as they near the outletopening A, to permlt of their introduction in the casing.

These valves are provided with vertical stems, N, O, and P,respectively, which are guided in corresponding openlngs W', W and W.The upper openin W, is made in a removable cap or plug in the wall ofthe draft tube.

The openings W, W, are formed in the upper valves themselves.

in the casin beneath the lower valve seat,'

and arm I provided with a slot M, in

which a link .or thrust member L, is pivoted. This member I, passesthrough a vertical bearing V, in the casing, and engages the lower valveand raises first the lower valve, and as the valve stems in turn engagewith the valves above, raises in succession the valves above.

The valves are made independent in their movements to a predeterminedamount, by leaving spaces above the stems in the open- 1ngs W, W, and W,when the valves are closed. The total amount of these spaces will beequal to the total amount that the lower Valve must be raised.

When all spaces above the valve stems are closed, the valves movesimultaneously, as one unitary structure.

In this device, if grains of sediment such as coffee grounds or othersediment should lodge on any one valve seat and prevent it fromcompletely closing, it would not prevent the other valves from actingindepend ently to close on their seats, or if any two seats shouldbecome leaky from wear or from the lodging of sediment thereon, thethird valve and seat would still operate to close their openingcompletely.

Springs Z, Z, and Z serve to close the erated by means of receptacles ofdifferent the lever B, is provided with a soft bumper strip -S, formedof felt or rubber which is preferably inserted in a groove or slot, T,in its engaging face.

To enable each valve to tilt upon itsv seat independently of the othersif a grain of a sediment should lodge upon its seat. Each opening W, andthe opening W are tapered or widened at their lower ends, to permitlateral movement of the stems.

Having described the invention what I claim as new and desire tosecureby Letters Patent is:

ll In a non-leaking valve mechanism for a faucet, in combinatlon, adispensing tube having a delivery opening, a vertical enlargementthereon forming a valve chamber,

a multiple number of valve seats in said chamber, arranged therein atdifferent levels, a corresponding number of valves for said seats, saidvalves provided with valve stems,

guide means for the stems of. the lower valves in the valves above, andguide means for the upper valve in the wall of said tube, and meansengageable by the utensil employed in drawing the fluid from said valve,for raising the lower valve, and thereby, in succession the valvesabove, one after the other, when all of said valves are raised togetherabove their seats, and'automatically acting means for returning saidvalves to their seats.

2. In a non-leaking valve mechanism, in combination with a draft tube,provided with an outlet opening, said tube enlarged intermediate of itsends to'provide a vertical valve chamber, spaced horizontalpartitions insaid chamber, said partitions provided with alined valve seats,corresponding valves for said sea-ts, axial valve stems for said valves,the upper valve stem provided with a vertical guide in the wall of saiddraft tube, and the remaining valve stems each provided with a verticalguide in the next adjacent valve above, each lower valve stem whenraised engageable with and operating to raise the valve above, and eachlower stem having a predetermined amount of vertical movement beforeengaging the valve above,

and means for raising the lower valve, and thereby in successlon raisingthe other valves.

3. In a dripless valve mechanism in combination, a draft tube, avertical valve chamber therein, a multiple number of spaced valve seatsin said chamber, arranged at different levels, and valves therefor,stems for said valves, the upper valves provided with guide openings, inwhich the stems of the lower valves are guided, and a separate guideopening in said tube forthe stem of the upper valve, said guide openingspermitting a predetermined amount of independent movement of each valveabove its seat,'an arm pivoted in said chamber, means for operativelyconnecting said arm with said lower valve, and an operating-lever forsaid arm.

4. Acomposite valve mechanism including in combination therein, adispensing tube having a delivery opening an enlargement thereon forminga valve chamber, independently movable valve parts seated in saidchamber, one part being actuated by the one preceding and in turnactuating the part succeeding, so that the various parts closesuccessively. and are open successively but in reverse order, atransversely and pivotally mounted actuating member in said chamber andadjacent to one of thesaid valve parts,

chamber wall, and means outside said wall 3 adapted to-be actuated bythrust of the receptacle to be filled from said opening for rocking saidmember.

6. In an automatic valve mechanism, in

combination, a valve chamber having inlet and outlet openings, spacedvalve seats in said valve chamber, and independently movable valvesseated thereon, said valves and valves seated being of different sizesand arranged in vertical and axial alinement, the seats and valve beingsuccessively smaller as they near the outlet opening, the said valvesbeing normally out of operative contact with each other, each valve;when raised serving to raise in turn the next larger valve, and meansfor operating the smaller valve.

7. In a valve mechanism, a valve chamber a multiple number of taperedvalve seats vertically spaced apart, therein, a valve resting upon eachtapered seat, each valve provided with a vertical stem, the stem of thelower valve having a limited vertical movement in the adjacent valve,and adapted to engage and raise the adjacent valve in turn when saidlower valve is raised from its seat,

answer and manually operated mechanism for raising said lower valve fromits seat, said valve chamber provided with a tubular guide openin in itswall in which the stem of the upper va ve is movably secured.

8. In a faucet in combination, a draft tube having a horizontal portionand a vertical portion, a valve chamber in said vertical portion, saidvalve chamber terminating in a discharge nozzle, upper and lower valvesin said. valve chamber, tapered seats for said.

valves, each valve provided with a vertical stem extending above thevalve, and the lower valve, provided with a vertical stem extendingbelow said valve, a guide therefor in said chamber below said lowervalve, a guide opening for the upper stem of said lower valve in thevalve above, and a guide opening for the valve stem of said upper valvein the upper horizontal wall of said draft tube.

Intestimony whereof, I hereunto set my hand this 23 day of December,1920.
